OpenRouter is a unified, OpenAI-compatible API aggregating hundreds of model providers behind one key. Free model variants (:free IDs) are genuinely free with documented platform caps — 20 requests/min and 50/day for accounts that have purchased under 10 credits, 1,000/day once you've purchased 10+ — while paid variants have no platform request cap. Fallback routing, per-key credit caps, and BYOK are built in.
free quota:free models cost $0, no card; 20 req/min; 50 :free req/day with <10 credits, 1000/day after buying $10+ credits (verified FAQ; failed reqs count). ~$1.5/mo equivalent at 50 req/day, ~1K tokens/call.

NVIDIA NIM's hosted API (build.nvidia.com / integrate.api.nvidia.com) serves a broad catalog of open-weight models — Nemotron, Llama, Qwen, DeepSeek, GLM and more — in an OpenAI-compatible shape, with a permanent free tier: API key at sign-up, no card, 40 requests/minute by default (200 RPM granted on request, per NVIDIA's developer forums).
free quotaFree tier is rate-limited (40 RPM default, 200 on request) rather than credit-based — no USD value to quantify.

Perplexity's API blends request and token pricing: Search API at $5 per 1,000 requests; Sonar at $1/$1 tokens plus a $5–$12 per-1K request fee that scales with search depth; and the new Agent API serving OpenAI, Anthropic, Google and xAI models at direct provider rates with no markup, plus per-invocation tool pricing (web_search $0.0025). Sonar is sunset after September 27, 2026 — the Agent API is the successor.
free quotaNo free tier on the API (checked 2026-09-16). Consumer Pro/Max plan credits (35K bonus + 10K monthly) apply to the app, not the API.
